SUPER FAIR 212 CONVERTER

What it is and why choose it

ALEXSEAL Super Fair 212 Converter C2127 is the polyamine-based hardener component for the ALEXSEAL Super Fair 212 epoxy fairing system. When mixed 1:1 with Super Fair 212 Base, it creates a solvent-free, lightweight epoxy filler designed for professional yacht fairing and filling, both above and below the waterline (when the system is correctly sealed and primed). The converter is engineered for reliable curing performance, forming a stable, sandable film that can be overcoated with compatible ALEXSEAL yacht coating products.

Main features

• Dedicated converter for Super Fair 212: Designed specifically for use with ALEXSEAL Super Fair 212 Standard Base and Thick Base.
• Epoxy polyamine hardener: Hardener based on polyamine/amino adduct chemistry for controlled curing of the filler system.
• Solvent-free system: The catalyzed Super Fair 212 system has 100% volume solids without reduction, supporting high-build fairing applications.
• Professional fairing performance: In combination with the base, provides excellent application, sanding and anti-sag properties for yacht substrates.
• Visual mixing control: Converter and base have different colors; once properly mixed, the filler appears as a homogeneous color, helping confirm thorough blending.
• Standard working time: Provides a pot life of approximately 1 hour at 15°C, 50 minutes at 20°C, 40 minutes at 25°C and 30 minutes at 30°C when used in the Super Fair 212 system.
• For above and below waterline systems: When used with Super Fair 212 and correctly sealed (e.g. with ALEXSEAL Finish Primer 442 below the waterline), the fairing system can be used on suitably prepared yacht hulls and superstructures.
• Available package sizes: Supplied in ½ gallon and 2 gallon containers to match Super Fair 212 Base packaging.

Applications and use cases

• Yacht fairing systems: Used with ALEXSEAL Super Fair 212 Base (standard or thick) as the hardener to create a solvent-free, epoxy-based lightweight filler for yachts that require filling and fairing.
• Above and below the waterline: The catalyzed Super Fair 212 system can be applied on appropriately prepared surfaces both above and below the waterline. When used below the waterline, the system must be sealed with ALEXSEAL Finish Primer 442.
• Metal substrates (with compatible primers): Super Fair 212 (base + C2127) is applied over correctly prepared and primed metal surfaces, such as those coated with ALEXSEAL Protective Primer 161.
• GRP substrates: Used as part of a fairing build over GRP surfaces primed with ALEXSEAL Super Build 302, Finish Primer 442 or Protective Primer 161, following the sanding and preparation steps specified in the technical data.
• Multi-layer fairing builds: Allows reapplication of Super Fair 212 over itself after the minimum dry-to-sand times and appropriate scratch sanding, before overcoating with compatible ALEXSEAL primers and topcoat systems.

FAQ

1. What is ALEXSEAL Super Fair 212 Converter C2127 used for?

   It is the standard converter (hardener) for the ALEXSEAL Super Fair 212 epoxy fairing compound, enabling the curing of the solvent-free filler on properly prepared yacht substrates.

2. How do I mix Super Fair 212 Base with the Converter?

   Mix at a ratio of 1:1 by volume or 1:1 by weight (Base : Converter). The filler color must become completely homogeneous, with no streaks of different color remaining.

3. Can I thin or reduce the Converter or mixed material?

   No. ALEXSEAL Super Fair 212 must not be reduced. It is a solvent-free system and should be applied without added thinner.

4. How long is the pot life after mixing?

   With C2127 Converter, pot life is approximately 1 hour at 15°C, 50 minutes at 20°C, 40 minutes at 25°C and 30 minutes at 30°C, depending on film thickness and application conditions.

5. When can I sand the Super Fair 212 system?

   With C2127, the mixed system is typically dry to sand after about 36 hours at 15°C, 24 hours at 20°C, 18 hours at 25°C and 12 hours at 30°C. Block sanding with P36–P120 is recommended.

6. Is Super Fair 212 Converter suitable for use below the waterline?

   When combined with Super Fair 212 Base and applied over correctly prepared substrates, the fairing system can be used below the waterline, provided it is sealed with ALEXSEAL Finish Primer 442.

7. What tools are recommended for applying the mixed filler?

   Apply the catalyzed Super Fair 212 using trowels, spatulas or straight-edge materials, building the thickness in thin layers to avoid air pockets.

8. How should I clean tools after use?

   Tools used with the catalyzed Super Fair 212 system should be cleaned with ALEXSEAL R4042 Epoxy Primer Reducer.

9. Is the Converter hazardous?

   Yes. According to its classification, it causes severe skin burns and eye damage, may cause an allergic skin reaction, and is very toxic to aquatic life with long lasting effects. Always follow the safety and personal protection guidance.

Section 8 – Individual protection measures

When handling ALEXSEAL Super Fair 212 Converter and the mixed Super Fair 212 system, follow these personal protective measures:

• Engineering controls: Provide good ventilation. Preferably use local exhaust and general extraction. If this is insufficient to keep particulates below applicable limits, suitable respiratory protection must be worn.
• Eye and face protection: Wear safety goggles to protect against splashes.
• Hand protection:
  • Use chemical-resistant protective gloves compliant with EN 374.
  • Recommended materials for short-term contact (splash protection): nitrile rubber or neoprene.
  • Minimum material thickness: > 0.4 mm.
  • Minimum breakthrough time: > 480 minutes.
  • Check glove suitability for the specific workplace and follow glove manufacturer’s instructions for use, storage, care and replacement.
• Skin and body protection: Wear clothing as usual in the chemical industry. Remove contaminated clothing immediately.
• Respiratory protection: None is normally required, but avoid breathing vapours, dust from sanding, particulates and spray mist. Use suitable respiratory equipment if adequate ventilation cannot be ensured.
• General hygiene measures: Do not eat, drink or smoke during work. Avoid contact with skin, eyes and clothing. Wash contaminated skin immediately and apply preventive skin protection (skin protection cream) if recommended. Organize work so that permanent wearing of protective gloves is not required.
